Explanation:
Permineralization
occurs when minerals carried by water are deposited
around a hard structure. They may also replace the hard structure itself.
Natural casts
form when flowing water removes all of the original bone or
tissue, leaving just an impression in sediment. Minerals fill in the mold,
recreating the original shape of the organism.
Amber preserved
are organisms that become trapped in tree resin
that hardens into amber after the tree gets buried underground.
Trace fossils
record the activity of an organism. They include nests,
burrows, imprints of leaves, and footprints.
Preserved remains
form when an entire organism becomes encased in
material such as ice or volcanic ash or immersed in bogs.
